Abstract: As an effective method in finding the global optimum, genetic algorithm (GA) is widely used in the structure optimization and other fields. It is of global convergence and parallelism. Based on the summary of application of GA in structure optimization, the application of GA in the energy dissipation structure was discussed from the aspects of some improved genetic algorithms and objective functions. Then, a combined optimization method based on GA and SAP2000 API was given. Some suggestions and prospects of the optimization of GA in the energy dissipation were presented.

Keywords: genetic algorithm; energy dissipation; SAP2000 API; optimization study
